My today's splinterlands daily quest was "Lyanna's call - win 5 ranked battles with the Earth Splinter". I completed it quite quickly, using Unicorn mustang, Gobling thief, Child of the forest and some fillin cards (depending on the mana amount)
I gained about 150 rating today and for my quest reward I got a Exploding Dwarf card.
